Abstract

The invention relates to a process for the control of the shifting process of a vehicle with electro-hydraulically actuatable friction elements for the shifting-over between different transmission stages in a vehicle with at least in addition a drive engine in which a current actual value is determined for at least one magnitude characterizing the shift process in each shifting process; the actual value is compared with an establishable and/or storable desired value; on deviation of the actual value from the desired value, the control pressure for the at least indirect influencing of the magnitude characterizing the switching process is adaptively changed by a determinable, calculatable or prescribable first correction value for the achieving of an optimal shifting behavior and the course of the altered magnitude is storable in each case as new characteristic curve of the desired values. The invention is characterized by the following features: in at least the shifting processes in which through a further adaption no satisfactory shifting courses can any longer be insured, at least one actual value-the drive turning rate-is determined for a magnitude characterizing the acceleration of the turning rate to be synchronized in force-flow direction in the drive line on the input side of the coupling at a time point after the beginning of the synchronizing process; the actual value either of the acceleration of the turning rate to be synchronized or of a magnitude at least indirectly characterizing the acceleration of the turning rate to be synchronized, or that of the turning rate to be synchronized, is compared with a desired value; on deviation of the actual value from the desired value the control pressure is altered by a second correction value until the desired value course of the turning rate to be synchronized is set in, and, moreover, the course of the control pressure characteristic curve is replicated at higher pressures.
